Elliott “A” Series (clamp-in) apparatus bushings are used to
construct air-insulated equipment that connects to the utility’s
underground shielded cable system with IEEE Standard
separable insulated connectors (i.e. elbows). Integral shielding
prevents “edge-of-hole” corona discharge. The live side of the
bushing is provided with unique square-edge skirts to resist
flashover when contaminated and wet. The large diameter
live end terminal pad (with female threads) provides for direct
contact of current-carrying parts and eliminates exposed sharp
threads, which could induce destructive corona discharge. In
addition to IEEE Standard 386 design tests, Elliott bushings
are design tested for thermal cycle withstand from +200° to
-200° F to assure long field life. Every bushing is production
tested “in-air” mounted in a grounded steel plate with an
insulated protective plug (or cap) installed on the interface to
accurately simulate operating conditions.
ELRIM Cycloaliphatic Epoxy Provides:
Nontracking, self-scouring, nonweathering performance

Elliott “A2” Bushings are advanced design clamp-in
bushings typically used to construct air-insulated
pad-mounted switchgear. Elliott “A2” bushings fit older-style
equipment constructed with clamp-in bushings and may
be used to upgrade or replace failed bushings on existing
equipment in the field. For new switchgear designs, we
suggest our higher performance “B” series bushings, which
offer superior electrical performance, higher mechanical
strength and numerous design advantages.
200 Amp Bushing Well - The #1101-225A2 bushing well is
a small-shank design that can be used to replace older Elliott
(and other manufacturer’s) clamp-in bushings using the
existing mounting hole and clamp ring. The #1101-225A2
bushing well can also be used to replace the discontinued
RTE® porcelain Safebreak Bushing when used with the
Elliott #1991-CRAR clamp ring adapter.
600 Amp Bushing - The #1201-625A2 bushing is a
large-shank design that uses the same mounting bolt

pattern and clamp ring as the small-shank bushing, but
requires a larger mounting hole. The #1201-625A2F is the
same bushing, with a special flange that allows the use of a
sealing gasket for in-oil application. It uses the same size
mounting hole as the #1201-625A2, but requires a different
mounting bolt pattern and clamp ring.
Index Slots - Elliott “A2” bushings feature a keying hole or
slots on the live end. Fuse clips and hinge kits are available
that bolt directly to the bushing conductor and key in the slots
to prevent rotation.
Conductor Connection - Female threads in the live end of
the conductor allow the attachment of live parts of almost any
thickness. The bolted connection of current-carrying parts
does not depend on current transfer through the fastener’s
thread-to-thread contact. Additional advantages of the bolted
connection are higher clamping pressure and elimination of
exposed sharp threads that could initiate corona.

to allow field replacement with standard tools. To assure
adequate strength for apparatus support, the bushing well
shall withstand a minimum cantilever loading of 150 pounds
for five minutes without damage. The bushing well interface

Elliott “A” Series Apparatus Bushings clamp in place utilizing
the mounting hole and hardware shown below. All mounting
hardware is located on the elbow side of the equipment
mounting plate to eliminate the possibility of reduced
phase-to-ground clearance.
Every Elliott Bushing is tested at the factory, mounted
in a grounded steel plate. A greased bushing well plug
(or insulating protective cap) is installed on the interface
to accurately simulate operating conditions. To prevent
contamination of the silicone grease, it is important to keep
the shipping cap in place until you are ready to install the
bushing insert (or elbow). Should the grease become
contaminated, thoroughly clean the interface and reapply
silicone grease before installing the bushing insert (or elbow).
NOTE: The shipping cap on the bushing well (or bushing)
should be left in place to prevent contamination of
the interface.

1. The bushing installs from the elbow side.
2. A clamp ring is placed on the bushing.
3. Lock washers and lock nuts are installed on the studs
(or bolts). The nuts should be tightened in a uniform
manner (rather than one-by-one in a random sequence).
Do not apply more than 90 inch-pounds torque to each
nut. The studs should be left unpainted to provide a
connection from the shielding to the grounded mounting
plate. If the bushing is mounted on an ungrounded
or insulated plate (such as fiberglass), a ground strap
should be attached to one of the mounting studs.
IMPORTANT:
Do not energize this bushing with only the shipping
cap in place. To do so would lead to failure of the
bushing and create a hazard to operating personnel.
This product is designed to be used only when it is
mated with an appropriate 15 kV or 25 kV Class bushing
insert (and/or elbow) conforming to the latest revision of
IEEE Standard 386. The bushing insert (and/or elbow)
should be installed in accordance with the instructions
supplied by the connector manufacturer.
